.'o all whom 'it may concern.'

Be it known that. I, Joux L.. Consta, a

eitizen of the VUnited States, residingat Jop lin, in the eouuty ot' Jasper and State ot Missouri, have invented u'uew'and useful Ineumatic Tire. ot' whieh the followingir is a speeitioation.

This invention relates to pneumatic tires and more particularly to means t'or mounting the same upon a wheel whereby injury to the tire body as a result of its frietional engagementwith the rim of' the wheel is reduced to the minimum.

Another object is to provide novel means for fastening the tiro to the wheel rim. said means being readily adjustable so as to seeur"or loosen the tire -relativoly to the rim. l A further object is to provide a wheel rim of novel form to which spokes may be uiekly attached, the Same bein" held against displacement by the tire retaining deviees.

'ith these and other objet-ts in view the invention consists of eer`litin novel features of eonstruetion 'und eornbnutions of parts whieh will be hereinafter more fully ,de- 'seribed and pointed out in the rlaims.

In the aeeonipanying drawings is shown the 'preferred form of the invention.

n said drawings:- Figure l is u section through a tiro embodying.;` the present iniprovenients, one of the. fastening.,r means used therewith lacing shown partly in seetion and nlrtly in elevation. Fig. 2 is a seetion on ine .r---a'E Fig. l. Fig. 3 is a set-tion on line 1/,i/, 'Fig'. l. lio. 4 is a detail View of a iol-tion of the :lellof the wheel and showlng the. spoke receiving slots therein. Fignj is a :seetion through a modified form of tire embodying the present improvement. Fig. (i is a detail view of a modified means for ,ex ending the wedgebands.

eferring to the gures b. characters of reference, 1 designates the fel y of the wheel1 the, same, being preferably in the form of a riln substantially U-shaped in section and -having annular flanges 2 designed to hear against.' and to be. brazed or otherwise. secured to the inner or eoncnved fare of the wheel'rim 3. rl`he edgeportions of this rim are curved inwardly toward the felly l and `are thiekened to produeel annular heads or velelwhers 4. Those portions of these. beads which lap 4the body portion of the run 3 form annular grooves or ehaunels and r these `f g'rooves are desi ned to receive the rounded heads 6 exten ing laterally from the inturnefl edge portions 7 ot' the outer tube H of the tire. This, outer tube-has fabric guard aprons 9 fastened upon the inner surtaee thereof and designed, when the heads are seated between the elenehers Jrand' the` t'elly l. to lap the elem-hers se as to prevent the inner tube I0 lt'rtu'n romiug;r into eontaet withtheni. t

ln order that the heads tt may he ,seenrely held in engagement with the eieuehers wedge bands l l are employed. Eaeh o't' these. bands is substantially eireulur in form and wedgeshaped in cross .seetion and one handis iusertible between the felly and eaeh inturned portion ot' the outer tube 8. as indie-ated partieularly in Fins. 2 and 3. Secured to one end of eneh band is a splitV tube 1Q t/onforming in outline to the. band and journaled within this tube is a ram lhaving a lever t4 extending beyond the tube. and whereby the ram ean be readily actuated. The cam is so shaped that when it. is turned in 4one direction so as to bring the lever \l 4 against the band 11 said eam willoperate. to spread the ends of the band apart. thus inereasng ita` diameter and eausin it to wedge tihtly` between 'the felly ,and the ge portion of tube 8 so as to foree the heafl (i firmly into the groove or ehannel l 5. Fornied within the felly are. Islots 15 extending there` into from opposite sides alternately, eaeh slot: bein" formed inone side portion of the telly and`terminating;r in an ey tti desiafned to receive the. head 17 of a spo e 1R. 'lliese eyes are so positioned `that when the bands 11 are iu plaee the eyes are (dosed thereby and the s okes thus` ing` detaelied. I

lt. is thought that the maniter of assemvbling: and detaching the parts of the tire will be fully understood from the forefron r deseriptiou. lqhould it be desired to detael either on(` of the heads` ti from the rim 3 the band ll eoperaliln.t with said. head is loosened hy swinging the arm l-l so as to lcui permit the ends of the hand 'to move toward V eaeh other. 'l`he band rau then be drawn outward from enga rement'. Iwith the tube 8 and tlwriuturmal talige portion of said tube and its head tt ean be readily removed from engagement with the rim :2 and its eleueher t. liy reversing: this operation the tube 8 eau be readily plared iu iosition.

Important-e is attarhet to the tart that. the rim :l and its eleuehers 4 are located within the tire tuhe 8 and tend to pull iliwardly l thereon instead of pushing inwardly thereagaiust as ordinarily. .The strain upon the tire is thus materially reduced and inasmuch as all of those portions of thc rim and clenchers which contact with. the tire are rounded, wear upon the tire is reduced to the minimum. lhe uard apron 9 serves to prevent the inner tu e from wearing upon the cleuchers and the riln 3 presents a broad, smooth, unyielding surface to said tube.

The construction heretofore described relates sc lely to all-metal wheels. Where it is desired to fasten the tire to a wheel having a wooden felly a construction such as disclosed in Fi r. 5 may be employed. By. referring to this figure it will be seen that the wooden felly 19 is surrounded by a metal band 20 and upon this band rests the U-shaped metal felly 21 which is held upon the wooden felly 19 by means of screws 22 which are extended through the wooden felly 19 and have their thrended portions engaging the felly 21. As shown 1n this figure the valve tube 23 is preferably arranged diagonally within the felly 21 so as to extend to one side of wooden fell y 19 without the necessity of notching or otherwise weakening said wooden felly.

In both of the forms heretofore described the wedge bands are utilized for the purpose of binding the edge portions of the tire upon the cleuchers. The bands as heretofore described consist of solid metal strips but, as

shown in Figs. 5 and (5 these bands may if` desired be formed of flattened tubes as indicated at. 2.9, said' tubes beingr substantially circular and having ears 30 extending inwardly from their ends. Links 31 and 32 are pivotally connected to these ears and are adjustably connected together as indicated at 33 by means of a detachable bolt fitted within one of the series of openings. Link $52?. is preferably formed with an arm 34 whereby the two links can be shifted so Aas to force apart the ends of the wedge band and increase the diameter coupling tongue 35 is riveted or otherwise secured within one of the ends of the band and is designed to loosely project into the other end thereof as shown in Fig. 6. It will be apparent that by Swingin the arm 34 in the direction of the arrow in ig. 6 the links V31 and 32 will be folded and draw the ends of the wed e band toward each other, thus loosening` tie tire. By reversin the movement of' the arm 34 the band will be ex ended so as to tightly wed e between the felriy and the edge portions o the tire so as to clamp said portion upon the adjoining clencher.

What is claimed is:

1. The combination with a wheel rim having inwardly extending annular clenchers, and a. felly interposed between the clenchers; of a tube embracing the' rim and clenchers,

thereof. A

and having inturned edge portions insertible between the felly and the clenchers, an annularly ex oscd non-inflatable circular wedge interpose' between the felly and each edge portion of the tube, for binding said portion 1n engagement with the adjoining clenchers and constantly exposed means upon said wedge for expanding the same to secure the edge ortions of the tube upon the clenchers.

2. 'lille combination with a wheel rim having inwardly extending annular clenchers and a felly -interposed between the clenchers; of a tube having inturned edge portions insertible between the felly and the clenchers,

tubular non-inflatable bands insertible between the felly and each edge ortion of the tube, the end portions of said and telescoping, coperatin means at the ends of each band for expanc ing the band annularly, said means and the inner edge portion of the band being constantly ex osed.

3. The combination Wit a wheel rim having inwardly extending annular clenchers and a felly interposed between theclenchers; of a tube having inturned edge portions insertible between the felly andthe clenchers, said felly having spoke-receiving openings therein open at one side of the felly, noninflatable circular Wedge shaped bands insertible between the felly and each edge portion of the tube, said bands constltuting` closures for the spoke-receiving openings, and cooperating means u on the end portions of each band for cxpan ing the band annularly, said means and the innen portions of each band being exposed at all times.

4. The combination with a wheel-rim having inwardly extending annular clenchers a'hd a felly interposed between the clcnchers; of a tube embracing the rim and the clenchers, and having inturned edge portions insertible between the felly and clenchcrs, a non-iniiatable circular wedge interposed between the fellyl and cach edge portion of the tube, coperatin means upon the end portions of each we ge for expanding the wedge longitudinally to bind the edge portions of the tube in engagement with the adjoining clencher, said coperatin means and the inner edge ortion of eac wedge being exposed at a l'times. 5. A retainin ring) for pneumaticutires comprising a tuular and wedge-shaped in cross sectlons, a telescopic connection between the end portions o the band,4 and cooperating means upon the end portions of the band for expan ing the b an annularly.

In testimony that 1 claim the foregoing as my own, I have hereto ailixd my signature 1n the presence of two witnesses.
